Hello,

I am seeking a firmware update example using Libcanard (STM32 MCU).  
I went through the [cyphal specification](https://opencyphal.org/specification/Cyphal_Specification.pdf) chapter 5.3.9 Node software update.

Please is there an example somewhere that I can use as my baseline for the node firmware update ?

Thanks.

Is there a demo example for this bootloader ?

There are some examples in the README that should be sufficient to get started. @ASMik might have some but I am not sure.
